An extension of the theory is made in order to apply it to helical systems and to study the properties of the zonal flow in the low frequency range. Further refinement of the theory is made incorporating the orbital effects of particles more precisely, and the role of neoclassical polarization current is identified.展开更多

It points out that most music halls and some opera houses in the world do not use sound amplifying,which is impossible for the current music halls in China. The experts from State Grand Theatre suggested the method of "architectural acousties first, electric acoustics for supplementing",the most important of which is how to master the supplementing of electric acoustics.展开更多
